Specification of Letters Patent.

Patented July 5, 1910.

Application filed January 18, 1910. Serial No. 538,578.

To all whom it may concern:

Be it known that I, J osnrrr J. Cosonovn, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin W ater-Closet Connections, of which the following is a specification.

This invention has relation to water closet connections and has for itsobject the provision of novel means for connecting a water-closet orsimilar article which rests on the floor, with the soil pipe so as toavoid the breaking of the soil pipe or of the floor flange of the closetor the floor flange of the connection or any other damage to the closetor its connections by the settlement of the soil pipe or the sinking orsagging of the floor.

The invention consists in providing a flexible floor plate or flangewhich has a seat, to receive the collar surrounding the closet outlet,the flexibility of the floor flange bein obtained by interposing ametallic ring, pret erably corrugated in concentric circles, between arigid ring resting on the floor and the soil pipe which corrugated ringwill support the coil pipe in proper alinement with the closet outletand yield under strain so as to allow of any required flexure of thesoil pipe or impairment of the symmetry of connected parts withoutbreaking the con nections or inducing leakage.

In the accompanying drawings illustrating my invention as applied to anearthenware water-closet and its soil pipe: Figure l is a verticalsectional view of a portion of a water closet and a portion of avertically arranged soil pipe with my improved connection appliedthereto. Fig. 2 is a horizontal section on the line w-m of Fig. 1,looking downward.

The bowl or closet designated 1, is of the usual or any desired type andis formed with theoutlet passage 2, terminating in a flange orprojection 3 which is threaded on the outside as shown at 4, to receivea correspondingly threaded collar 5, which latter is slightly taperedeither conically or on curved lines toward its lower end, so as to restin a correspondingly tapered seat formed in the upright ring flange 6 ofthe horizontal floor plate 7 of the soil pipe 8. The rigid flange ring7, is secured to the base 9 of the closet bowl by bolts 10 in the usualmanner.

The rigid floor flange ring 7, is a separate structure from the soilpipe 8, which is in the usual form of a section of lead tubing of aninterior diameter corresponding to the diameter of the outlet passage ofthe closet. The rigid section 7 is a cast metal ring with an openingconsiderably larger in diameter than the outside diameter of the soilpipe and said pipe and rigid section 7 are connected together by meansof the ring 11, which is preferably made from sheet copper of suitablethickness, and is corrugated with concentric corrugations 12, whichimpart to the ring the required flexibility. The edges of the corrugatedring are secured to the rigid floor plate section 7, and to the soilpipe by soldering.

In fitting the soil pipe to its proper position with relation to thecloset, the rigid section 7, with the bolts 10 passed through it, isfirst laid on the floor so as to surround the opening in the floorthrough which the soil pipe is to pass. The soil pipe is then passedthrough the floor opening to about the level of the floor line and thecorrugated ring 11 is then slipped over the end of the pipe and itsedges soldered to the pipe and if separate from the section 7, to theinner edge of the section 7. The rigid section and the flexible ring 11may be soldered together. before being placed in position on the floor.The closet bowl carrying the threaded collar 5, is now placed inposition, with the collar 5 resting on the tapered seat of the flange 6,and the bolts 10 which pass upward through holes 12 in the closet base,are tightened up by means of the threaded cap nuts 13.

As will be seen, none of the weight of the closet is supported by thesoil pipe, nor is any part of the closet connection brought into suchcontact with or relation to the soil pipe as to affect or be affected byany change in the position of the soil pipe with reference to itsalineinent with the closet outlet opening. Any unevenness in the flooror abnormal condition or relation of the soil pipe to the closet iscompensated for by the flexible corrugated ring, which yields underslight strain without breaking or rupturing the parts connected theretoor opening up any seams or subjecting the parts forming the closetconnection to the soil pipe to strain or other injurious eflects.

The application of the corrugated flexible ring embodies the noveldesideratum of a the closet and soil pipe, which willenable installedand maintained in satisfactory relation and insure a water tight jointunder the arying conditions which are encoun- The corrugation inconcentric circles of the flex-ible ring is suggested as the best 7 formin: which the rlng may be made but I other forms may be adopted withoutdey 1 vof the floor'plate parture from the invention.- collar and Thetapered correspondingly tapered seat are not essential elements in thestructure, asit is obvious that the flexible ring 1 1 maybe applied toclosets in which the bowl is otherwise supported thanaas hereindescribed and shown.

7 Having: described: my invention, I claim and desireto secure byLetters Patent:

1 1 The combination with the soil pipe of water-closet, of a flexiblemetallic floor plate. g r

- 2. The combination of a water-closet, a soil: pipe and flexiblefloorplate secured to the: soil pipe. it

and a soil pipe the closet, soilpipe and joint elements to be beaess 3..The combination with a watercloset of a floor plate composed of a rigidmetallic ring upon which the closet is supported and a flexible metallicring which is connected to the soil pipe and to said rigid metallicring.

(7 tered in the first installation of the closet and afterlapse of time.

4. The combination with a soil pipe of a floor plate comprising aflexible, metallic,

" corrugated ring.

5. The combination" with a soil pipe of a floor plate comprising aflexible, corrugated metallicringsecured to the pipe and a ri id ring.surrounding and secured to the flexible ring- 6.. The combination with awater-closet haying: atapered metallic ring surrounding its outletopening, of: a. soil pipe and a flexible floor plate secured to the soilpipe, and having a tapered seat to receive the tapered ring of. thecloset.

In testimony whereof I have afiixed my signature, in presence of twowitnesses.
